You often want to make the repeat size of your patterns exactly to spec, which is now easy, thanks to SymmetryMill 2 displaying the repeat size when you edit the control path. You can also turn on the repeat size display by simply hovering your mouse over the control path. In either case, the repeat size shows up in the top section of the Source Image window.
SymmetryMill 2 is almost here, and it comes with a new automatic pattern generator, advanced blend modes, a bevy of new filters, numerous improvements, and, importantly, a modern technology behind the familiar user interface.
As a pattern junkie, you may know how to capture the structure of a repeating pattern in a diagram; that is, determine to which of the seventeen symmetry types a pattern belongs. Yes, we are talking about surface patterns, or wallpaper patterns, whose type is determined by what mathematicians call the plane (2D) symmetry groups. Turns out all pattern schematics are not made equal and, surprisingly, the most simple diagram, which is also the most useful for the non-mathematically inclined, is also the least known or, we might even be tempted to say, a well-kept secret.
Traditionally, because you are dealing with symmetries, your pattern schematics would show symmetry operations, probably combined with boundaries of repeating units (“unit cells” or “fundamental domains”), and often made more intelligible by superimposing actual patterns produced by a simple asymmetric bit (a line, a comma, or a letter of an alphabet). Here are a few examples of the standard approach, which we show mostly to help you fully appreciate a simpler one that’s coming up next:
